When Facebook unveiled Timeline for the first time and we caught a glimpse of it at their F8 developer summit, it was clear that Facebook has big plans for this feature. Timeline was a major upgrade for the social network, and it was definitely going to stay. What we did not know, was how far Facebook would keep developing it, before rolling it out to the public permanently. Well, the wait is over, and stating today, Timeline is an official Facebook feature, available to all Facebook users. The final rollout of timeline took Facebook four months from its first preview.
In these four months, Facebook acquired Gowalla possibly to improve Timeline, or to integrate location services (Facebook places, in this case) with Timeline in some way. Timeline was also released on 15 December as an opt-in feature in New Zealand, where you had to enable Timeline for your account by yourself, if you wanted to use it. This time though, Timeline will be the default view on your profile. Although you can select to opt-out of Timeline for a few more days (at facebook.com/about/timeline), eventually, your account will be upgraded to use Timeline.
I have been using Timeline for quite some time now, using a trick that was revealed right after the first preview of Timeline (irrelevant now). Timeline has some interesting UX aspects that make it wonderful for a walk down memory lane. It gives more meaning and organization to the stream of Facebook posts, presenting it as a meaningful stream of thoughts over time.
Timeline is available on both the Facebook website, and on the Android Facebook app. If you have not seen Timeline on your profile yet, you will get it very soon. Tag your photos properly and clean up your albums for a meaningful Facebook Timeline experience on your profile. Here is the Facebook Timeline introduction video for those did not get a chance to see it yet.
